6-Way Linux Desktop 2D/3D Performance Comparison On Ubuntu 14.04 LTS

Our latest benchmarking of Ubuntu 14.04 is looking at the 2D X11 and 3D OpenGL performance of six different desktop environments when benchmarked on Ubuntu 14.04 LTS. The tested desktops included Unity, Xfce, KDE, LXDE, GNOME Shell, and Openbox.

It always intrigued me how some tests perform better in composited, worse in non-composited and vise versa. It makes sense, but it really shows how there isn't a perfect graphics arrangement, depending on what you do. But, if you've got multiple GPUs, one configured for desktop use and the other configured for GPGPU tasks, I guess you get the best of both worlds.

It's a shame KDE is still behind, I wonder if the wayland ports of it will get any better, or if maybe there's 1 small tweak that makes a big difference (such as vsync). I'm well aware KDE performs the worst, but my hardware is good enough that it doesn't really have enough of an impact on me for me to complain about.

I would assume 'Suspend Desktop effects for fullscreen windows" was not checked, as usual. If this is the case, I would suspect that enabling that would bring back in line with the other DEs.

The things is. This test was testing the defaults. And I suspect the default is still the stupid non-redirect for fullscreen applications. (I don't know for sure since I haven't used kde in a year, xfce) Is there anyone who could confirm if this is the case or not?

KDE doesn't un-redirect by default for fullscreen apps, which imho, is the right option. If you enable that tickbox, games typically run a lot faster. Apparently the redirecting penalty on wayland can be pretty much zero :-)
